Title: (EN) OIL-RETAINING SINTERED BEARING AND METHOD OF PRODUCING THE SAME
Abstract: front page image
(EN)

An oil-retaining sintered bearing in which friction coefficient can be reduced and a sliding property as a bearing can be improved by supplying a sufficient amount of oil to a sliding surface and preventing the supplied oil from moving to an interior from the sliding surface; a sliding surface 3 supporting an outer peripheral surface of a shaft and a helical oiling surface 4 around a shaft axis of a bearing hole are adjacently formed on an inner peripheral surface of the bearing hole into which the shaft is inserted; a surface open rate at the sliding surface 3 is not larger than 10%; and a surface open rate at the oiling surface exceeds 10%.
